Researchers revealed a study last week that showed that people who regularly do resistance training (aka weight lifting) added an additional 40 minutes of sleep! Study participants were comprised of people who had difficulty regularly getting over 07 hours of sleep, and the addition on weight lifting, increased their sleep times by almost 10 percent. Participants that did aerobic exercise only experienced a 23 minute increase. In other words, Weight lifting doubled the amount of additional sleep they got.
So why does weight training improve the quality of sleep? It could be related to the fact that resistance exercise releases the hormones that are associated with high quality sleep. It could also be related to the the fact the weight training takes a more substantial toll on the body that requires deeper, more comprehensive recovery to bounce back from. Simply, more intense the work, the more intense the recovery needed to bounce back from it.
